The interaction between tea polyphenols and host intestinal microorganisms: An effective way to prevent psychiatric disorders

This 2021 review discusses the relationship between tea polyphenols and gut microorganisms, breaking down the potentially preventative role of tea polyphenols in psychiatric disorders via modulation of host intestinal microorganisms. Tea polyphenols make up the most bioactive components in tea extracts, and have been reported to regulate the composition and function of the intestinal flora. The microorganisms in the gut also interact with tea polyphenols by enhancing its bioactivity. The metabolites produced can control intestinal microecology and promote health. It is said that dysfunctioning of the microbiota-gut-brain axis (the interactions between the gut, its microbiota, and the brain) forms the main basis of depression. These abnormalities may influence and possibly directly cause psychiatric disorders. [NPID: tea, polyphenols, gut microbiota, gut, intestine, depression, disorders, MGBA]

Guts imbalance imbalances the brain: A review of gut microbiota association with neurological and psychiatric disorders

The connection between the brain, gut bacteria, and neurologic-associated diseases has drawn more attention in the past decade. Gut microbiota plays a significant role in mental and cognitive development, neurogenesis, emotions and behaviors, and the progression of neuropsychiatric illnesses, evident by numerous preclinical and clinical research studies demonstrating the gut microbiota’s ability to impact the […]

A psychology of the human brain-gut-microbiome axis

Allen et al. (2017) point out that research may have indicated the connection between the gut microbiota and cognition as well as various other stress-related behaviours, but the underlying mechanisms are not yet known. This review outlines the role psychology has to play in understanding the brain-gut-microbiome axis, with a focus on human psychology and […]
